Starting from Baudrillard's analysis of the ideological character inherent in all consumption, touristic consumption, for many reasons ,has a special place in this social semantic. Here, advertising plays an important if not essential role because tourism is a product consumed outside of normal time and daily social space. Therefore the social semantic asserts itselfless through the product itself than through its representation: the discourse of advertising. But advertising discourse is plural, each form having its own ideology, competing with others. Behind the commercial competition lies a competition of social classes, but with a new typology, no longer based on the capital/favor relationship. Four ideological models are analyzed and illustrated with their advertising messages: the traditional model, the clerical/executive model, the youth model, and the “intellectual class” model. 相似文献

This article explores the influence of food product packaging on consumers’ sensory expectations and perceived newness of the product. Two experiments examine to what extent consumers use product typicality, graphical representations, and package typicality in evaluating new food products. Study 1 finds that (1) a typical flavor induces more positive expectations of pleasantness, taste, color, and smell, and (2) the presence of graphic representation on product labels increases perceived pleasantness but does not affect sensory expectations. Study 2 indicates that the product seems newer in the absence of a package (label-only condition), but when the product packaging is presented, an atypical package conveys more newness than a typical package. These results provide practical guidelines for the design and introduction of innovative food products. 相似文献

We define continuous-time dynamics for exchange economies with fiat money. Traders have locally rational expectations, face a cash-in-advance constraint, and continuously adjust their short-run dominant strategy in a monetary strategic market game involving a double-auction with limit-price orders. Money has a positive value except on optimal rest-points where it becomes a ??veil?? and trade vanishes. Typically, there is a piecewise globally unique trade-and-price curve both in real and in nominal variables. Money is not neutral, either in the short-run or long-run and a localized version of the quantity theory of money holds in the short-run. An optimal money growth rate is derived, which enables monetary trade curves to converge towards Pareto optimal rest-points. Below this growth rate, the economy enters a (sub- optimal) liquidity trap where monetary policy is ineffective; above this threshold inflation rises. Finally, market liquidity, measured through the speed of real trades, can be linked to gains-to-trade, households?? expectations, and the quantity of circulating money. 相似文献

This paper investigates the impact of window dressing on stockbroker analyst evaluation of a company's annual accounting numbers. A new methodological approach is used involving a laboratory experiment in which a large sample of experienced investment analysts drawn from five of the top London houses processes real company accounts. The research was conducted in the first half of 1990 at the end of a long bull market. The participating analysts were not overly concerned about the quality of published accounting information and creative accounting was not then viewed as a serious problem. Contrary to our prior expectations we found little evidence of window dressing adjustments being made by the subjects in general. However, those subjects who did correct were significantly more experienced. Possible explanations for our results and potential implications for capital market behaviour and information processing are discussed. 相似文献

An increasing number of collaborative learning environments is based on shared workspace systems using two-dimensional graph-structured visual representations such as argumentation networks and concept maps. We propose an integrated framework that allows for flexibly specifying a wide range of visual languages and plugging in components for operational semantics, adequate feedback and intelligent support. The generic application CardBoard provides card-based user interaction and collaboration by means of different languages in shared workspaces. To enhance modifiability, the interfaces between the distributed heterogeneous system components, particularly between intelligent components and user interfaces, have been standardised. 相似文献

Reward-based crowdfunding campaigns are commonly offered in one of two models via fundraising goals set by an entrepreneur: “Keep-It-All” (KIA), where the entrepreneur keeps the entire amount raised regardless of achieving the goal, and “All-Or-Nothing” (AON), where the entrepreneur keeps nothing unless the goal is achieved. We hypothesize that AON forces the entrepreneur to bear greater risk and encourages crowdfunders to pledge more capital enabling entrepreneurs to set larger goals. We further hypothesize that AON is a costly signal of commitment for entrepreneurs yielding a separate equilibrium with higher quality and more innovative projects with greater success rates. Empirical tests support both hypotheses. 相似文献

维修管理已经经历了一系列的重大变革。这个典型的以知识为中心的方案把维修工作提高到战略水平。与以知识为中心的战略思想相比较,公司开展的合理化工作也更加受到重视。任务对外协作、技术的加速发展、由于故障或失效造成损失的最少化,以及维修活动复杂程度的增加,这些对于维修管理领域推广以项目为导向(Projict—Oriented)的方案都作出了重要贡献。维修项目的成功与否影响整个公司的成功。对于项目的成功将介绍几种不同的解释,并将探讨确定如何判断项目成功的方法。最后综合迄今为止的研究成果,提出优秀的维修模式。 相似文献

Summary. We study a strategic market game associated to an intertemporal economy with a finite horizon and incomplete markets. We demonstrate that generically, for any finite number of players, every sequentially strictly individually rational and default-free stream of allocations can be approximated by a full subgame-perfect equilibrium. As a consequence, imperfect competition may Pareto-dominate perfect competition when markets are incomplete. Moreover - and this contrasts with the main message conveyed by the market games literature - there exists a large open set of initial endowments for which full subgame-perfect equilibria do not converge to
-efficient allocations when the number of players tends to infinity. Finally, strategic speculative bubbles may survive at full subgame-perfect equilibria.Received: 24 January 2002, Revised: 21 February 2003, JEL Classification Numbers:
